Have you checked the fluid level? The Jacks on my 98 Bounder wouldn't work. The "Jacks Down" light wouldn't go off. Checked the fluid level with my finger and it seemed good. After trouble shooting for an hour, I decided to add fluid until it ran out of the filler port. The jacks worked. 1/4" of fluid level makes a difference.
